An artist produces an effect in virtue of the distinctness with which he sees the objects he represents, seeing them not vaguely as in vanishing apparitions, but steadily, and in their most characteristic relations. To this Vision he adds artistic skill with which to make us see. He may have clear conceptions, yet fail to make them clear to us: in this case he has imagination, but is not an artist. Without clear Vision no skill can avail. Imperfect Vision necessitates imperfect representation; words take the place of ideas.

Foolish critics often betray their ignorance by saying that a painter or a writer "only copies what he has seen, or puts down what he has known." They forget that no man imagines what he has not seen or known, and that it is in the selection of the characteristic details that the artistic power is manifested.

A man may be buoyed up by the efflation of his wild desires to brave any imaginable peril; but he cannot calmly see one he loves braving the same peril; simply because he cannot feel within turn that which prompts another. He sees the danger, and feels not the power that is to overcome it.

Philosophy and Art both render the invisible visible by imagination. Where Sense observes two isolated objects, Imagination discloses two related objects. This relation is the nexus visible. We had not seen it before; it is apparent now. Where we should only see a calamity the poet makes us see a tragedy. Where we could only see a sunrise he enables us to see

If clear Vision be indispensable to success in Art, all means of securing that clearness should be sought. Now one means is that of detaining an image long enough before the mind to allow of its being seen in all its characteristics. The explanation Newton gave of his discovery of the great law, points in this direction; it was by always thinking of the subject, by keeping it constantly before his mind, that he finally saw the truth. Artists brood over the chaos of their suggestions, and thus shape them into creations.

Simplicity of structure means organic unity, whether the organism be simple or complex; and hence in all times the emphasis which critics have laid upon Simplicity, though they have not unfrequently confounded it with narrowness of range.

Every one who has seriously investigated a novel question, who has really interrogated Nature with a view to a distinct answer, will bear me out in saying that it requires intense and sustained effort of imagination. The relations of sequence among the phenomena must be seen; they are hidden; they can only be seen mentally; a thousand suggestions rise before the mind, but they are recognised as old suggestions, or as inadequate to reveal what is sought; the experiments by which the problem may be solved have to be imagined; and to imagine a good experiment is as difficult as to invent a good fable, for we must have distinctly present — clear mental vision — the known qualities and relations of all the objects, and must see what will be the effect of introducing some new qualifying agent. If any one thinks this is easy, let him try it: the trial will teach him a lesson respecting the methods of intellectual activity not without its use.

No man really thinks and feels monotonously. If he is monotonous in his manner of setting forth his thoughts and feelings, that is either because he has not learned the art of writing, or because he is more or less consciously imitating the manner of others. The subtle play of thought will give movement and life to his style if he do not clog it with critical superstitions. I do not say that it will give him grace and power; I do not say that relying on perfect sincerity will make him a fine writer, because sincerity will not give talent; but I say that sincerity will give him all the power that is possible to him, and will secure him the inestimable excellence of Variety.

The first obligation of Simplicity is that of using the simplest means to secure the fullest effect. But although the mind instinctlvely rejects all needless complexity, we shall greatly err if we fail to recognise the fact, that what the mind recoils from is not the complexity, but the needlessness.

In Science the paramount appeal is to the Intellect — its purpose being instruction; in Art, the paramount appeal is to the Emotions — its purpose being pleasure. A work of Art must of course indirectly appeal to the Intellect, and a work of Science will also indirectly appeal to the Feelings; nevertheless a poem on the stars and a treatise on astronomy have distinct aims and distinct methods. But having recognised the broadly-marked differences, we are called upon to ascertain the underlying resemblances. Logic and Imagination belong equally to both. It is only because men have been attracted by the differences that they have overlooked the not less important affinities.

The art of a great writer is seen in the perfect fitness of his expressions. He knows how to blend vividness with vagueness, knows where images are needed, and where by their vivacity they would be obstacles to the rapid appreciation of his thought.

I would not have the reader conclude that because I advocate plain-speaking even of unpopular views, I mean to imply that originality and sincerity are always in opposition to public opinion. There are many points both of doctrine and feeling in which the world is not likely to be wrong. But in all cases it is desirable that men should not pretend to believe opinions which they really reject, or express emotions they do not feel. And this rule is universal. Even truthful and modest men will sometimes violate the rule under the mistaken idea of being eloquent by means of the diction of eloquence. This is a source of bad Literature.

It is impossible to deny that dishonest men often grow rich and famous, becoming powerful in their parish or in parliament. Their portraits simper from shop windows; and they live and die respected. This success is theirs; yet it is not the success which a noble soul will envy. Apart from the risk of discovery and infamy, there is the certainty of a conscience ill at ease, or if at ease, so blunted in its sensibilities, so given over to lower lusts, that a healthy instinct recoils from such a state. Observe, moreover, that in Literature the possible rewards of dishonesty are small, and the probability of detection great. In Life a dishonest man is chiefly moved by desires towards some tangible result of money or power; if he get these he has got all. The man of letters has a higher aim: the very object of his toil is to secure the sympathy and respect of men; and the rewards of his toil may be paid in money, fame, or consciousness of earnest effort. The first of these may sometimes be gained without Sincerity. Fame may also, for a time, be erected on an unstable ground, though it will inevitably be destroyed again. But the last and not least reward is to be gained by every one without fear of failure, without risk of change. Sincere work is good work, be it never so humble; and sincere work is not only an indestructible delight to the worker by its very genuineness, but is immortal in the best sense, for it lives for ever in its influence. There is no good Dictionary, not even a good Index, that is not in this sense priceless, for it has honestly furthered the work of the world, saving labour to others, setting an example to successors.

I wish to call special attention to the psychological fact, that fairies and demons, remote as they are from experience, are not created by a more vigorous effort of imagination than milk maids and poachers. The intensity of vision in the artist and of vividness in his creations are the sole tests of his imaginative power.

Our native susceptibilities and acquired tastes determine which of the many qualities in an object shall most impress us, and be most clearly recalled. One man remembers the combustible properties of a substance, which to another is memorable for its polarising property; to one man a stream is so much water-power, to another a rendezveus for lovers.
